lMPFtOVED MOP-HEAD.

Specification forming part of Letters Patent No. 47,642, dated May 9,1865.

To all whomA it may concern.-

Be it known that I, NELSON HOMES, of Laona, in the county of Chautauquaand State of New York, have invented a new and Improved Mop-Head; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, referencebeinghad to the accompanying drawings,forming a part of this specification, in whichy Figure l is a side viewof my invention; Fig. 2, a side view of the same, partly in section;Fig. 3, a horizontal section of the same taken in the line .fr x, Fig.2.

Similar letters of reference indicate like parts.

This invention relates to a new and im proved means for moving theadjustable bar or jaw of the mop-head, whereby the same may be readilymoved for securing the mop in the head and releasing it therefrom, andat the same time prevented from movin g casually.

A represents the iixed jaw or portion of the 1nop-head, which may bedescribed as a bar forming three sides of a quadrangle, and two arms, aa, which are secured in a crossbar, b, on a nut, B, in which a screw, C,works, said screw being at one end of a socket, D, in which the woodenhandle E of the mop-head is fitted.

The outer part of the screw G, or, rather, the rod on which the screw iscut or formed, is prolonged and ofless diameter than the screw, as shownat F in Fig. 2, and on this part F there is iitted a sleeve, G, withinwhich and around F a spiral spring, H, is placed, said spring having atendency to keep the outer end of the sleeve G, which is provided withratchet-teeth c, pressed against similar teeth, d, at the inner side ofthe movable or adjustable jaw I, through which a journal, e, at theouter end ot' F, passes centrally, said journal having a head, f, at itsouter end to retain the jaw upon it. The ends ofthe jaWI are notched toreceive the sides of the fixed jaw A, which sides serve as guides forit.

The part F of the screw-rod has two longitudinal slots, g g, made in itat opposite sides, to receive spurs h on the sleeve G, and at the innerend of each slot g2 there is a notch, i, to admit of the spurs h beingfitted or turned therein so as to keep the teeth c of the sleeve inwardand free from the teeth d of the jaw I when desired, as shown in Fig. 2.When the sleeve G is held in this position, the socket and screw may beturned, and in consequence `of the latter working in the nut B it willbe seen that the jaw I may be moved toward and from the jaw A, the outerside, ax, thereof, which is the jaw A proper. When the jaw I is movedfrom the side a of A, the mop is inserted between ax and I, and thesleeve G is then released by turning it so that the spurs li will bemoved out from the notchesi and in line with the slots "g, when thespring H will throw the sleeve outward and cause its teeth to engagewith those of the jaw I. With the sleeve G in this position the screw Cmay be turned in the direction to force the jaw I toward the mop andcause it to be firmly grasped and held between a and I, as the teeth ofthe sleeve will slip over those of jaw I 5 but the sleeve cannot turn inthe opposite direction, and hence the casual receding of the jaw I from0L is prevented, and consequently the accidental liberation of the mop.

In order to remove the mop from the head, the sleeve G is pressed inwardso that its spurs 'h will reach the inner ends of the slots g, and

the sleeve then turned so that the spurs will catch into the notches i,when the jaw Imay be moved inward from a* and the mop removed.

I claim as new and desire to secure by Letters Patent-f i The screw C,in connection with the nut B and sleeve G, the latter being providedwith ratchetteeth c, and arranged on the part F of the screwrod with aspiral spring, H, the part F being provided with slots and notches toreceive the spurs of the sleeve, and connected with the jaw I, as shown,and the jawprovided with ratchet-teeth b, all arranged substantially asand for the purpose set forth.
